Brief summary: In this experimental study, genome editing and in vitro pancreatic differentiation of human pluripotent stem cells (SC) were used to generate ZNT8 loss-of-function (LOF) SC-β-cells. These cells showed accelerated functional maturation, increased insulin secretion and improved resistance to metabolic stress. Transplantation of ZnT8 LOF SC-β-cells into mice with preexisting diabetes significantly improved their glucose levels.<...

To read the full abstract: Proc Natl Acad Sci U S A. 2020; 117(4): 2187–2193. PMID: 31932420.Since their discovery ~70 years ago, glucocorticoids (GC) have been widely used to elicit a systemic anti-inflammatory response, and currently play a major role in the treatment of asthma and other inflammatory diseases (1). However, unresponsiveness to GC in some individuals i...
